IMPROVEMENT IN HANGERS FOR PLOW-COLTERS..

Specification forming part of Letters Patent 218,617, dated August 19,1879; `application filed March 24, 1879.

To all whom it 'may concern:

Be it known that` I, ALBERT H. BURLIN- GAME, of Sparta, in the county ofRandolph and State of Illinois, have invented a new and usefulImprovement in Colter-Hangers; and I do hereby. declare that thefollowing is a full, clear, and exact description ot' the same,reference being had to theaccompanying drawings, .forming part of thisspecification, in which- Figure 1 is a side elevation of my improvedcolter-hanger; Fig. 2, a vertical sect-ion and partial elevation of thesame, a portion of the arm which swivels with the Wheel-colter which itis intended t'o support being broken away. Fig. 3'is a top view of thecolter-hanger complete. Fig. 4 is a top view of the arm which support-sthe` wheel-colter, the check bolt or stop which prevents it swivelingbeyond a given extent either to the right or left being shown by dottedlines.

The main part of my invention consists in a vertical bolting-platetwhichis adapted for being bolted to the side of a plow-beam and having ahorizontal segmental extension-plate with adjusting-teeth and a pendentscrew-pin below the beam, in combination with a tubular sleeve adaptedto be tted around the pendent pin, and having a nearly-circular headwith adjusting-teeth on its upper side, which fit into the teeth of thesegmental plate, and also having two lateral brackets, to which theswiveling arm of the colter-wheel is pivoted, one of said brackets beingnearly in form of a quadrant, and provided with a segmental slot inwhich a check bolt or stop is applied and made adjustable horizontallyto the extent required for the purpose of bringing the arm of thecolter-wheel parallel with the beam or landside of the plow. By thispart of my'invention the brackets of the colter-hanger,.together withthe swiveling arm and wheel-colter, can be swung around beneath the beamin either an almost complete circle or a very small part of .suchcircle, and the wheel-colter, with its swiveling arm separate from thebrackets of the hanger, can then be readjusted from an oblique positionwith respect to the side of the beam to a position parallel with theside of the beam, and then,when thus adjusted, the

arm and colter can swivel to a limited extent either to the right orleft. f

My invention further consists in certain details of construction andminor combinations of parts, as will be presently described andspecifically claimed herein. i

In the accompanying drawings, A represents v a vertical bolting-plateprovided with two or more series of diamond-shaped boli-holes, aa,whereby the improved colterhanger B is adapted for being bolted'to. the`side of a plow-beam, one inch to three and a half inches thick. Thisplate is provided'at its bottom just below the plow-beam with ahorizontal segmental extension-plate, al al, and with a vertical pendentpin, A1, whiehextends from a half-round thickened port-ion,` A2, on theouter side of the plate above the segmental extension a, and just belowtheplate it takes a cylindrical form. The segmental extension al isprovided with V-shaped adjusting and locking teeth a2, and the pin A1 atits lower end is reduced in diameter and provided with a clampingscrew-nut, a3.

D is a tubular sleeve having an enlarged head, d, of nearly circularform, and with V- shaped teeth all on its upper side, matching the teetha2 of the segmental plate al. This tube is fitted on the pin A, and whenits teeth t snugly between the teeth a2 it is confined by the nut a3.

0n the upper and lower ends of the tube D lateral extensions or bracketsDl D2 are provided, and in the same pivot-holes for a pivot, e, areformed. Between these brackets aforked swivel-arm, E, intended forcarrying an ordinary rolling-colter, is pivoted4 bythe pin e, so Yas tobe adjusted to a considerable extent, and, after being adjusted, have alimited swiveling motion. The bracket or extension D is in form of aquadrant, and its top surface is horizontal, and through it a slot ofsegmental form is provided, as shown by the letter d2. In this slot acheck bolt or stop, F, is arranged, so thatits large oblong head f willstandbeneath the plate, and its fastening-nutf come on top of the plateD. With reference to the head fof the bolt F, the swivel-arm E is formedwith short prongs e2 e2 at its rear end, and these prongs stand onopposite sides of thehead f,

far enough from one another to allow the arm E a limited swivel movementeither to the right or left.

From the foregoing description it maybe seen that the tubular sleeve l),with the other movable parts below the plate A al a2, can be swungaround in a horizontal plane beneath the plow-beam, this beingaccomplished by simply loosening the nut a3 and lowering the tube untilits teeth dl are below the teeth a2 of t-he segmental extension a., andswinging the tube around as far'as desired, and then raising it on thepin A' and setting up the nut a3. This adjustment having been made, thecolter and its swiveling arm E stand oblique or diagonal to the beam orland-side of the plow, and it is necessary to readjust the arm E, so asto bring the colter parallel with the beam and land-side of the plow;and to accomplish this the nut f' is loosened and the check or stop boltF moved around in the seg mental slot d2 until the colter stands in linewith the beam, and then the nut f' is set up, so as to secure the boltin its adjusted position, and thereby hold the colter and its arm E fromswinging around too far.

It will be understood that the arm E and the colter attached to it areallowed, together, a slight amount of swveling movement between theprongs e2 e2, and that this movement is limited by the stop-bolt F beingstruck either by the right or left hand prong e2. This limited swivelmovementis permitted in order to have the colter accommodate itself tothe plow while turning to go back over the field.

With my improved hanger for colters the very nicest., as well as thegreatest, necessary adjustments can be effected without separating` theparts, and in the most expeditious manner,

and besides this the main parts can all be cast and the hanger furnishedat small cost.

What I claim is- 1. The combination of the plate A, segment al, pin A,sleeve D, extension D, bolt F, and colter-arm E, all in the manner andfor the purpose herein described.

2. The tubular sleeve D, formed with the toothed head d d and perforatedbrackets or extensions Dl D2, substantially as and for the purposedescribed.

3. The tubular sleeve D, provided with teeth d1, whereby the colter canbe locked in any position to which it may be adjusted, and also providedwith the segmental slot d2, in combination with the bolt F andcolter-arm E, whereby the colter, with its arm, can be adj usted afterit is swung around and locked by the teeth of the sleeve D,substantially as described.

4. The colter-arm provided with a forked end, e2, iu rear of its pivote, in combination with the tubular sleeve D, provided with the extensionD1, having the slot alz and the adjustable stop-bolt F, substantially asdescribed.

5. The colter-arm forked, as at 62,011 its rear end, said forked endbeing in rear of the pivot c, and serving for interlocking the colter,in combination with the device F, which adjusts it to a positionparallel with the plow-beam, and also limits its vibration,substantially as described.

Witness my hand this 21st day of March, A. 1). 1879, in the matter of myimproved hanger for colters.
